This is certainly not the first time we have seen missile launchers attached to a gun. The Israelis have been doing it for years using the Typhoon gun mount which is the basis for the current 25mm Mk38s as used on the Webber class. .

The dimensions of the British missile and American APKWS and Hellfire are provided for comparison.

The Martlet has the option of proximity fusing and Laser Beam Rider guidance (in addition to semi-active and IR homing), that probably makes it more effective against air targets, particularly smaller ones like drones. It has been used successfully against a target drone. It also has a longer range than APKWS, but is probably more expensive. Its biggest disadvantage from our point of view is that it is not in the USN inventory.

I am not advocating for this particular weapon, but both Israel and the Royal Navy have seen the wisdom of combining missiles with auto cannon.

It minimizes manning requirements in that a single operator can control both missiles and guns.

It minimizes space requirements

It eliminates the need to pass the targeting information from one fire control to another as the target enters gun range.

Unlike separate systems it probably also means you cannot engage two targets simultaneously.

We need a gun for the signaling, the proverbial shot across the bow, but it is not the best way to neutralize a threat. In an installation like this, the missile is more accurate, has longer range, and is less likely to cause collateral damage.

My feeling is that the Coast Guard would be better off with Hellfire than APKWS. We probably will not have to engage a large number of small targets as the Navy might, but our targets might be larger and this might be the largest weapon available to us. Either APKWS or Hellfire would be an improvement over what we have. The nominal effective range of the 25mm Mk38 is 2,700 yards (2,457 m). The APKWS would double this and the Helfire would triple the effective range. Either would allow us to engage from outside the likely effective range of any improvised weapon system that might be used in a terrorist attack, which I estimate would not exceed 4,000 yards.

When the Mk38 Mod3 was announced, there were indications BAE intended to add a capability to launch APKWS from the mount. I am still hoping.

The Army is developing turrets to mount on armored fighting vehicles that can include launchers for AIM 9X Sidewinder air-to-air missiles and AGM-114 Hellfire II air to ground missiles and a 30mm gun. I do think they tie into a sensor network.

If you are going to do AAW, you either need a radar or at least a data link input such as Link 16.
